Lower gas prices in Colorado and nation called
Average retail gasoline prices in Colorado fell 3.2 cents last week, averaging $3.

Well being consistent means being able to admit if you are wrong and not being able to rewrite history or facts. If the GOP (as a whole) and many politicians (in general) did that, then how would they be able to play to many of their fear mongering voters?
